What are some ways that you can measure the weight of an object?
The equation used to calculate the weight of an object is F = ma. “F” is the force in Newtons, “m” is the mass in grams and “a” is the acceleration due to gravity. Put the values of the problem into the equation. For example, multiply the mass of the object times the acceleration due to gravity, or F=(3g)(9.81 m/s^2).
What’s the weight of a mountain?
Most average mountains have weights that are in the billions of pounds. The estimated weight of the largest mountain, Mount Everest, is more than 350 trillion pounds. The difficult part about determining how much a mountain weighs is not just the height and the size, but it is also the material.
How do you find weight using density?
Density is useful in calculating the weight of substances that are difficult to weight. You can determine its weight simply by multiplying the density by the size, or volume, of the item. Write down the volume and the density of the item you’re measuring.
How many ways can you measure a mountain?
There have been in vogue three methods of measuring elevations of mountains above adjacent plains or above the level of the sea: The geodetic method, the barometric method, and the boiling point method. Of these, the geodetic method is the oldest and at the same time the most accurate of recent time.
How did they measure mountains in the old days?
Trigonometry had been used by the Greeks to measure tall structures and by Victorian surveyors to measure the tallest mountains before we moved onto satellites. However, even satellites measure elevation by essentially implementing the same principle – drawing triangles.
How can I measure weight without a scale?
Good household objects include hand weights. Or look to your kitchen, where packages of dry food are printed with weight measurements of their contents. You can also use containers of water (a gallon of water weighs 8.35 pounds).
How do you measure weight of gold without a scale?
Stick lumps of stick tack to both the bottom of the measuring cup and the top of the jar lid. Place the jar lid, overturned, on one side of the ruler and place the measuring cup on the other. Adjust the position of both objects, moving them closer to or further from the center, until you can balance the ruler again.
How do you calculate the weight of Mount Everest?
It gives you 547 million square feet which when multiplied by the height (11,500 feet) results in a volume of 2.1 trillion cubic feet. When multiplied by Eureka and density, we get an estimated weight of 357 trillion pounds.
How much would I weigh on Mount Everest?
According to some quick Wolfram Alpha calculations, the difference in gravity per the equation above means that the gravity at the top of Mount Everest is 99.72\% as strong as the gravity at sea level. Thus, if something weighed 1000 lbs at sea level, it would weigh only 997.2 pounds at the top of Mount Everest.
How do you find density without mass?
A simple method based on the moment of forces and Archimedes’ principle is described for finding density without measuring the mass and volume of an object. The method involves balancing two unknown objects of masses M1 and M2 on each side of a pivot on a metre rule and measuring their corresponding moment arms.
How do you find volume without density?
Usually, if the density is not given then we can use the density of water i.e. $1g/cc$ as a standard or reference but here only mass is given, so the other way to find volume is the water displacement method.
How do you calculate the weight of a 30 degree mountain?
For our 30 degree mountain the radius of the base r is root 3 times h so our formula simplifies to V = pi * h^3. Taking the height as 10000 ft we get V = 3.14 *10^12 cubic feet. A cubic foot of granite weighs about 170 lbs/ft^3, so the weight of our model mountain is about 530 * 10^12 lbs or 2.6 * 10^11 tons.
How do we measure the height of mountains?
Given the distance and the angle, basic trigonometry was used to calculate the mountain’s height relative to the observer. Today, measuring altitude is a lot easier thanks to GPS, but a major wrinkle remains: mountains, especially the Himalayas, do not stay constant.
How do you calculate the volume of a mountain?
Rock has a typical density of about 2700 kg/cu.m. Slopes typically average 30 degrees in rugged terrain, so if a mountain has height H, it’s radius is 1.73H or H sqrt (3). So if we consider the mountain to be a cone of height H and radius Hsqrt (3), then the volume is 1/3 (base) (height) = 1/3 (pi 3 H^2)*H = pi H^3.
What is the weight of a model mountain?
A cubic foot of granite weighs about 170 lbs/ft^3, so the weight of our model mountain is about 530 * 10^12 lbs or 2.6 * 10^11 tons. Rock has a typical density of about 2700 kg/cu.m. Slopes typically average 30 degrees in rugged terrain, so if a mountain has height H, it’s radius is 1.73H or H sqrt (3).
